NEEDLE.

Specification of Letters Patent.

Patented May 9, 1922.

Application filed May 29, 1920. Serial No. 385,252.

To all whom it may concern:

Beit known that I, GUIno PI'I'ONI, subject of the King of Italy,residing at Rochester, in the county of Monroe and State of New York,have invented new and useful Improvements in Needles, of which thefollowing is a specification.

This invention relates to needles and has for an object the provision ofa needle having an eye of novel formation which will permit of its beingreadily threaded.

Another object is the provision of a needle whose eye is provided with anormally closed entrance slot, through which the thread may be readilypassed into said eye, and will be prevented from slipping out.

With the above and other objects in view, the invention includes thefollowing novel features and details of construction, to be hereinaftermore fully described, illustrated injthe accompanying drawings andpointed out in the appended claim.

In the drawings:

Fig. 1 is a View of a sewing machine needle provided with an eyeconstructed in ac cordance with the present invention.

Fig. 2 is an enlarged view of the eye end of the needle showing amodified form of the invention.

Fig. 3 is a view of a further modified form of eye shown in connectionwith a different type of needle.

Fig. 4C is an enlarged view of one end of the needle showing a stillfurther modified form of eye.

Referring to the drawings in detail and especially to Figure 1. thereference character 10 indicates the shank of a needle, 11 the point and12 the eye. The eye 12 is normally closed. and is provided with apointed member 13 which extends into the eye, being located along thecentral longitudinal line of the needle. Extending into the shank of theneedle from one side thereof is an entrance slot 14, the said slotpassing through the extension 13 centrally of its point and providingspring fingers 15 which serve to normally close the entrance to the eye.

The needle may be readily threaded by inserting the thread in theentrance slot 14 and passing the same between the spring whereupon itwill be fingers 15 into the eye,

against return passage through the held slot.

In Figure 2 there is illustrated a slightly modified form of theinvention in which the entrance slot 14: has extending from its oppositewalls spring fingers 16 which contact. at their free ends and serve toclose the slot and act as an additional safeguard against the passage ofthe thread.

In Figure 3 the needle shown is of a different type having a point i?and an eye 18 located at a remote distance from the point. Extendinginto the eye 18 is a pointed projection 19, while the slot 20 providedin the said shank of the needle has an entrance slot into the eye. Alsoextending into the eye 18 is a spring finger 2].. one end. of which issecured at the en d of the slot 20. the finger being so shaped to formone wall of a continuation of the slot 20, with the free end of thespring finger contacting with or located adjacent to the pointed ontension 19.

The form of the invention shown in Figure 4 in similar to that justdescribed, except that the slot 20 is provided. with inwardly extendingspring fingers similar to the fingers l6 desrribcd in connection withFigure 2.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes properly fall within the scope of the appended claim.

Having described the invention what is claimed is A device of the classdescribed comprising a pointed shank provided with an. eve and having acurved taperingslot formed there in and communicating with said eye. apair of converging pointed members extending into said eye upon oppositesides of: said slot, and a plurality of spaced opposed spring fingersextending from the inner converging walls of said pointed members.

In testimony whereof I aflix my signature.

GUIDO PITONI.
